E-AVDS-GSM(-P)
GSM Automatic Voice Dialer
INSTALLATION AND OPERATION
MANUAL
INTRODUCTION
The E-AVDS-GSM GSM Automatic Voice Dialer is used to send voice or text GSM or SMS alert messages from an ENVIROMUX
Enterprise Environment Monitoring System (SYSTEM) to any user’s cell phone or device capable of receiving voice or SMS
messages. Before connecting the E-AVDS-GSM to the SYSTEM, a GSM SIM card configured for GSM voice messaging and SMS
messaging must be installed in the E-AVDS-GSM following instructions below.
The E-AVDS-GSM-Pincludes a 12VDC power supply for connection to E-MINI-LXO or any other SYSTEM where an external power
supply will be needed.
Cell phone Mini SIM card for GSM modem
A SIM card or Subscriber Identity Module is a portable memory chip used in some models of cellular telephones. It can be thought of
as a mini hard disk that automatically activates the phone (or in this case the E-AVDS-GSM ) into which it is inserted.
SIM cards are available in three standard sizes. The first is the size of a credit card (85.60 mm × 53.98 mm x 0.76 mm). The next,
“standard” size is a miniature-version with a width of 25 mm, a height of 15 mm, and a thickness of 0.76 mm. Finally, the “micro”
version measures 15 mm x 12 mm x 0.76 mm. The E-AVDS-GSM accepts the mini SIM card.
Verify with your service provider that their Mini SIM card will work with GSM / 3G GSM type modems before purchasing their Mini SIM
card.
Note: Make sure the Mini SIM card is for GSM communication (not CDMA), configured to send GSM voice and SMS
messages, and that it is not locked (some SIM cards are "locked" to search for a specific IMEI number of the phone to
operate).
OPEN THE E-AVDS-GSM
There are four tabs that hold the case together. Two on the top side, and two on the bottom side. To open the case for Mini SIM card
installation, press down firmly on the seam of the case near the tabs on one side of the case and snap the case halves apart.

CONFIGURE THE JUMPERS
Configure the jumpers on the E-AVDS-GSM for connection to either the Normally-Closed (N.C.)or Normally-Open (N.O.) relay contact
on the E-xD. In the image below, the jumpers are set for connection to the N.O. terminal.
To set the “normal” relay state to Normally-Open, apply the J2 jumper to the center and right pin, and J1 jumper to the center and left
pin. In this configuration, a relay closure will trigger an alert state, activating the dialer.
To set the “normal” relay state to Normally-Closed, apply the J2 and J1 jumpers to the center and left pins. In this configuration, a
relay open condition will trigger an alert state, activating the dialer.
NOTE: The “VOLTAGE” jumper position is not used in conjunction with the E-xD.
With the Mini SIM card installed and the jumpers properly set, re-assemble the case and attach the supplied antenna to the port on the
side of the auto dialer.

In some cases you will need to know what IMEI number is associated with your E-AVDS-GSM. Follow these steps to locate and
record the number.
1. While the case is still open (after installing the Mini SIM card), remove the 4 screws that secure the rear circuit board to the front
circuit board.
2. With the screws removed, carefully pull the rear circuit board off of the front circuit board. Lift the circuit board straight up to
separate them.
3. Gently lay back the circuit board and locate the IMEI number on the chip on the backside of the rear circuit board.
4. Record the IMEI number
and carefully re-assemble the

E-AVDS-GSMConfiguration
By default, the E-AVDS-GSM will perform a self-test upon start up after which it will enter working state indicated by the display of a “1”
or “2” and a flashing decimal point on the lower right corner of LED display.
A slow flashing decimal point indicates normally working state.
A rapid flashing decimal point indicates there is no GSM communication.
If an SMS message and/or voice message have been programmed and saved, and a phone number and contact method have been
programmed into at least one “Ex” button, the E-AVDS-GSM will automatically alarm as soon as it receives an alarm signal.
Use the following to configure programming, enter or review phone numbers, program SMS messages and/or program voice
messages. (If GSM signal level is 0, please check antenna position and installation)
To exit programming mode at any time, press <ENTER>. The LED will display a “1” or “2” to indicate a normal working state.
1. Enter Programming Mode
Press <PAUSE> + private password (4 digits) + <ENTER>
Note: Default password: 0911
Example: PAUSE+0911+ENTER.
If password input is correct, “5” will be displayed and the dialer will enter the programming mode.
If password input is incorrect, “E” (meaning error) will be displayed and the dialer will return to a normal working state.
2. Program and Review Service Provider Contact Number
By default, the E-AVDS-GSM will automatically search for and program the contact number of the service provider when the unit is
powered ON.
To check that a number is programmed, in a programming state (in “5” state): press <3> and <0> . The dialer will display the service
provider phone number followed by two beeps.
To clear and refresh the service provider phone number, press <0> and then <ENTER>. The LED will display “A” to indicate a correct
input. It will then automatically search for and re-program the service provider contact number.
To manually enter the contact number, press <0> and then enter the service provider contact number, followed by <ENTER>.
For example: 0+15860305205+ENTER,
The display will return an “A” is the input has been done correctly.
We recommend letting the E-AVDS-GSM automatically acquire the service provider contact number.
3. Program Alarm Buttons and Alarm Method

microphone. Speak clearly and within 6 inches of the microphone for the best sound quality. When the recording times out, two
beeps will be heard. (To end the voice message recording manually, press <8> when finished.) The recording will then be played back
to you.
Review the Recorded Voice Message,
In programming mode, press <3> + <1> . A “P” will be displayed indicating the message being played. When finished, two beeps will
be heard.
5. Program SMS message
To program an SMS message to be sent by the E-AVDS-GSM, you must first send the message to the
E-AVDS-GSM via text message.
A. In programming mode, press <2>.
B. From a phone with a text messaging feature, send a message not more than 70 characters in length (any additional characters
will be ignored by the dialer) to the SIM card. (The phone number of the SIM card should have been provided by the service
provider that sold you the SIM card.)
C. Upon receipt, the LED will display “A” and two beeps will be heard. It will then return to programming mode (“5”).
If this takes too long and the process times out, an “E” will be displayed. Wait 2 minutes and then repeat the procedure.
Note: The buttons on the dialer are not operable while waiting for message content. You will need to wait 2 minutes if the
dialer times out.
The failure of the dialer to receive the message may be caused by a loss of communication. If repeated attempts fail, try
power-cycling the dialer, allow it to restore connection with the service provider, and try this procedure again.
If no SMS message is programmed, the default SMS message sent will be “DA-911 ALARM”.
6. Test Programmed Alarm
In programming mode, press <4> and then the desired <Ex> button to be tested. The display will illuminate the upper 4 segments in a
small “o” during the test. The test will last 15 minutes. Check the device dialed for the message that was sent. (For SMS messages,
this may take several minutes.) To cancel the test, press <ENTER>.
If “0 “appears, this indicates a successful test and then system will return to state “5”.
If “E” appears, this indicates the communication attempt failed and the dialer will then return to programming mode (“5”). Try the test
again.
If test fails after repeated attempts:
verify the phone number entered is correct.
make sure the SIM card is properly installed
verify the service number provider contact number is correct,
verify the SIM card/mobile phone is in service
check the GSM antenna connection and that the signal quality is normal.
7. Program Voice Alert Stop Method
In programming mode, press <5> and then input 0/1/2 (desired stop method (described below)), and <ENTER>. The “A” will be
displayed to confirm correct input, and then return to state “5”.
